CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of Israeli Patent Application No. 231686 filed Mar. 24, 2014, entitled “Automatic scent selection”, which is hereby incorporated by reference in its entirety for all purposes.

TECHNICAL FIELD

The present disclosure relates to scent dispensers.

BACKGROUND

Smell is one of the strongest and most primal of all the human senses. Many researches shows that smell can influence human thoughts and behavior more than expected. Just like verbal, dress and physical cues, scent, may help people to convey impression and sometimes influence the way people perceive each other.

In perfumery, notes are descriptors of scents. Notes are generally separated into three classes: top notes, middle notes and base notes. The classes denote groups of scents that may be smelled with respect to the time after the perfume application. A top note scent may be a scent that is perceived immediately or within a short time after application of a perfume. A top note scent may typically consist of relatively small and light molecules. The top note may be characterized by a relatively noticeable scent. The top note may be of high volatility (e.g., evaporation coefficient of about 1 to about 14). The top note may be fast evaporating, such as within approximately seconds of dispensing. The top note may be suitable for conveying a desired initial impression to others.

The perfume industry is pushing the wealth of the scent world to practically every aspect of everyday life and successfully spreading into hospitality, retail, consumer packaged goods, beauty, healthcare, real estate and other worldwide marketplaces.

Emerging scent applications, such as digitally transmitting and receiving scent, are becoming more affordable and therefore more available in the consumer marketplace. One popular example is delivering a specific scent for enhancing videogame experience. Artificial recreation of a smell by synthesizing chemical molecules is one enabling technology of these scents on demand applications.

One technical problem dealt with by the disclosed subject matter is to automatically personalize a scent of a user based on an event or the person the user is about to encounter. People may wish to use different perfume for each person they meet and the type of events they encounter throughout the day. Replacing a perfume every few hours or twice a day may not fulfill social needs of the user throughout the day. Additionally or alternatively, a compact and efficient manner to personalize a scent worn by a user may also be desired in view of the growing awareness of the impact smell has on the way people are perceived by others.

One technical solution is determining an appropriate scent for an event that is associated with the user and applying the scent on the user. In some exemplary embodiments, facial recognition may be employed to allow personalization of the scent based on identity or other characteristics of a person that the user is about to encounter. The disclosed subject matter may utilize a dispenser, capable of applying the appropriate scent for the event. An event may be, for example, a detection of a gesture by the user, an identification of a smell, an identification of a location, a facial recognition, a volitional action of the user, a combination thereof, or the like. The characterization of an event may be, for example, characterizing a person such as a gender of the person, an identity of the person, an age of the person, a demographic profile of the person, or the like; type of a place; time of a day; a combination thereof, or the like. a combination thereof, or the like. Additionally or alternatively, characterization of an event may be based on a type of relationship between the user and a person in a social network such as for example Facebook™, Twitter™, Linkedin™ or the like.

In some embodiments, the disclosed subject matter may recognize an approaching person and utilize a facial recognition module to characterize the approaching person. A scent can be selected and applied on the user prior to the user meeting the approaching person. As an example, a perfume may be applied on the wrist of the user, just in time before the forthcoming handshake with the approaching person. In some exemplary embodiments, the timing in which the scent is applied may be based upon the distance and the movement direction of the approaching person. Additionally or alternatively, the scent may be applied based on a gesture which is part of a non-verbal greeting between the user and the approaching person, such as for example the user extending his hand for a handshake or spreading his hands to hug the approaching person.

In some embodiments, the dispenser may be a fast release dispenser. In some embodiments, the dispenser may be a fast release dispenser configured to apply a specific perfume from a plurality of perfume cartridges. Each one of the perfume cartridges may be associated with specific event. Additionally or alternatively, the dispense may be operatively coupled to a scent synthesizer configured to synthesize a scent on-demand.

In some exemplary embodiments, the dispenser may dispense fast evaporating perfume which may evaporate relatively fast and will not interfere with another scent, should it be applied later on. Fast evaporating perfume may enable use of the disclosed subject matter to provide for an on-demand personalized scent which may be modified on demand and relatively frequently.

One technical effect of utilizing the disclosed subject matter is equipping the user with automatic device capable to personalize the scent of the user. In some exemplary embodiments, the user may be enabled to convey different impression to different people, in different location, or at different time, by using different scents. The user may use one fragrance suitable for a romantic meeting and another for a business meeting.

Another technical effect of utilizing the disclosed subject matter is providing retail businesses, such as an eclectic department store, with automatic scent selecting device to improve the performance of the salesmen, wherein the selection of the scent is based on customer's profiling. Upon characterizing the customer's profile, such as the customer's buying habits, an appropriate scent may be applied on the salesperson who will interact with the customer. The scent may be selected so as to improve the salesmanship of the salesperson with respect to the customer. As an example, different scents may be used to convey different messages to the customer, such as one scent may be used to increase the reliability of the salesperson while another scent may be used to encourage purchase of more luxurious items.

Referring now to FIG. 1, showing a flowchart diagram of a method in accordance with some exemplary embodiments of the disclosed subject matter.

In Step 100, an event may be detected. The event may be used to trigger the system to select and apply a specific scent on the user. A detecting component such as 220 of FIG. 2 may be utilized to detect the event. In some exemplary embodiments, the event may be a gesture by the user. Additionally or alternatively, the event may an identification of smell. Additionally or alternatively, the event may be arriving at a predetermined location. Additionally or alternatively, the event may be identifying an approaching person approaching to the user. In some exemplary embodiments, the event may be a verbal greeting and nonverbal greeting such as for example, a handshake, a hug, a combination thereof, or the like. In some exemplary embodiments, an event may be a part of a non-verbal greeting, such as for example, when the user stretches his or her arm with an intention to shake the hand of an approaching person. Additionally or alternatively, the detecting component may be configured to indicate an event if, for example, the detecting component is recognizing a forthcoming or potential physical contact with a person.

In Step 110, facial recognition may be performed. The facial recognition may be performed by a facial recognition component, such as 230 of FIG. 2, operatively coupled with a camera, such as 252 of FIG. 2. The facial recognition may determine characterizations of a person such as a gender of the person, an identity of the person, an age of the person, a demographic profile of the person, a relationship with the person a combination thereof, or the like. In some exemplary embodiments, the facial recognition may be performed to characterize a plurality of people. Additionally or alternatively, the facial recognition may be performed to detect an approaching person and estimate the time to encounter that person based on the distance and direction between the user and the person.

In Step 120, a scent may be determined. The scent determination may be performed by a scent determinator such as 240 of FIG. 2. The determination of the scent may be based predefined rules. In some exemplary embodiments, the rules may be defined by the user. As an example, the rules may define a different scent in response to different event types, to different characterization of people, or the like. In some exemplary embodiments, event of different types may trigger different scents. As an example, different gestures may trigger different scent selection. As another example, a different scent may be selected in response to an event which involves meeting a person. The scent may be, for example, selected based on characterization of the person (e.g., such as determined in Step 110)

In some exemplary embodiments, the scent determination may be based on a characterization and scent data base, such as 250 of FIG. 2. The data base may comprise set of rules defined by the user for associating the scent to an event type or properties thereof. As an example, the rules may define a first scent to be selected in response to meeting the user's spouse, a second scent to be selected in response to meeting a woman, and a third scent to be selected in response to meeting men of estimated high demographic background. Additionally or alternatively, the scent determination may be based on social connectivity between the user and a person in a social network such as for example Facebook™, Twitter™, Linkedin™ or the like.

In some exemplary embodiments, the determination of Step 120 may result in a selection of a specific scent to be applied in response to the event. Additionally or alternatively, Step 120 may determine a duration in which the scent is to be dispensed.

In some exemplary embodiments, the determined scent may be selected based on availability of perfumes. As an example, in case a perfume cartridge is depleted a replacement scent may be used instead.

In some exemplary embodiments, the determined scent may be a top note. The scent may be selected from available top note scents or from potentially synthesizable top note scents.

In Step 130, dispensing instruction may be communicated to a dispenser, such as 240 of FIG. 2. The instruction may indicate the selected scent of Step 120. In some exemplary embodiments, information may be communicated in addition to the selected scent, such as for example a dispensing duration, an instruction to synthesize the scent, an instruction to apply the scent, a duty cycle of reapplying the scent, or the like. The communicated instruction may be communicated via wired communication, wireless communication, or the like.
